Hi there,

My client wants to add a list of linked activities (ActVc) to a new window. I've created new keys in ActVc, added RecordList2 to DClass, and the records are displayed.

However, they do not appear as I would like. I need a list similar to the one in CUDClass for linked contacts or in AgreementDClass for linked reservations:

Double-clicking should open the linked record.
When selecting "Window" and then "Save Window" from the menu, the sorting state should be saved.
The list of linked records only works with the waction DClassUpdateWindowSubset, where I set the necessary subset. But how can I set a subset (using the field Code of the new register, which is the main key) without this waction, similar to what's done in CUDClass or AgreementDClass? I've thoroughly reviewed all the source code, but I couldn't find anything related to this. It seems like these windows are hardcoded in the core, which is not ideal.
